An air-floated apparatus, such as a lawn mower or vacuum cleaner, includes a housing having an open bottom and an air intake opening. The housing is adapted to cooperate with a support surface beneath the housing to define a substantially enclosed chamber. At least one air impeller is provided for pressurizing air within the chamber sufficient to float the housing above the support surface. An axle and first and second support wheels mounted with the axle are coupled to a back portion of the housing by first and second attachment members. Respective first ends of the first and second attachment members are mounted for co-movement with the housing and respective second ends of the first and second attachment members are mounted for pivotal movement with respect to the axle and wheels. Pursuant to this configuration, the housing is able to float with respect to the axle and wheels when the housing is floated above the support surface by air pressure in the chamber with the wheels in contact with the support surface. An adjustment device is provided for adjusting the position of the housing along a vertical axis relative to each of the first and second wheels when the housing is floated above the support surface.
